Two-conductor 18 AWG
twisted, shielded cable with
two-socket plug and
fluorosilicone elastomer
boot at one end, terminal
lugs at the other
Used with monitors
The 125065-12 is a dedicated dual-core sensor cable assembly serving as the connection interface for the 330500 Velomitor piezoelectric vibration velocity sensor. This assembly functions as a crucial signal transmission medium within rotating machinery condition monitoring systems.
Equipped with a fluorosilicone elastomer boot
Transmission distance up to 1,000 feet (305 meters)
Equipped with a 2-pin socket connector compatible with the 330500 sensor
Bently Nevada Velomitor Piezo-velocity Sensors are designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The 330500 is a specialized piezoelectric accelerometer that incorporates embedded integrated electronics in a solid-state design. Because the 330500 incorporates solid-state electronics and has no moving parts, it does not suffer from mechanical degradation and wear, and can be mounted vertically, horizontally, or at any other angle of orientation. As an indispensable signal bond within the aforementioned integrated vibration measurement architecture, the 125065-12 specialized cable assembly establishes a highly reliable physical pathway. Since the sensor itself eliminates any moving parts and supports unrestricted multi-angle omnidirectional installation, this 12-foot two-conductor shielded cable is physically reinforced to complement these features, offering superior bending flexibility to withstand continuous physical stress even when deployed long-term on vertically, horizontally, or obliquely oriented vibrating machinery surfaces.

Oil and Gas
Used for bearing housing vibration monitoring of large natural gas compressors and main crude oil transfer pumps on offshore drilling platforms, oil extraction plants, and long-distance pipelines.
Thermal Power
Employed in the vibration protection of bearing pedestals for small to medium-sized steam turbines, gas turbines, large boiler feedwater pumps, induced draft fans, and forced draft fans.
Hydroelectric Power
Used for operational vibration and structural fatigue monitoring of upper/lower guide bearing housings, thrust bearing housings, and scroll casings in hydroelectric generating units.
Pulp and Paper
Used for absolute casing vibration measurement and predictive maintenance of paper machine drying cylinders, press section large rolling bearing housings, pulpers, and high-consistency pulp pumps.
Rail Transportation
Applied in the absolute vibration analysis of motor casings for high-power traction motor bearings, gearbox test benches in metro/high-speed rail vehicles, and during EMU bogie overhaul processes.
During the operation and maintenance of the 125065-12, strict adherence to the following protocols is mandatory. First, because this model features an unarmored cable, you must never over-stretch or forcefully bend the cable during field routing, ensuring its bend radius meets specifications and running it entirely through metal conduits or cable trays to prevent physical abrasion or mechanical crushing. Second, since this cable is developed for standard non-explosion-proof environments, it is strictly prohibited to route it inside the 21128 velocity transducer aluminum explosion-proof housing, as the mismatched physical structure will cause cable twisting and damage. Lastly, when connecting to the 330500 velocity sensor, verify that the front fluorosilicone elastomer boot is fully seated and locked to achieve optimal moisture and oil resistance, and ensure the rear terminal ring lugs are firmly tightened onto the 3500 system monitor terminal blocks to prevent loose contacts caused by severe machinery vibration.
The 125065-12 is a dedicated Velomitor velocity sensor connection cable manufactured by Bently Nevada, responsible for transmitting machinery vibration signals collected by the sensor to industrial monitoring systems.
Which sensor is the 125065-12 primarily compatible with?
This cable is specifically developed for Bently Nevada's most widely used 330500 Velomitor piezo-velocity sensor, achieving a perfect and tight lock with the connector on its top.
What are the internal conductors and configuration of the 125065-12?
It contains two 18 AWG stranded copper conductors internally and utilizes a twisted, shielded pair configuration to extremely effectively resist field industrial electromagnetic interference.
What special protection does the sensor-end connector of the 125065-12 feature?
The end of the cable connecting to the sensor features a straight two-socket plug and comes with a corrosion-resistant fluorosilicone elastomer boot to block oil and moisture penetration.
How is the monitor-end of the 125065-12 terminated?
The monitor-end of this cable comes pre-terminated with terminal ring lugs from the factory, allowing engineers to connect it directly to the 3500 system terminal blocks.
